Will it break down quickly like Bifen does under strong UV rays? Looking for an exterior product that will last at least 30 days under extreme 100+ degree heat.
It will be difficult for any product to last over 30 days in extreme heat and direct sunlight, however, we would recommend an encapsulated product for the longest residual. Demon Max has an oil base, while the Bifen IT is a water-based insecticide (Bifen XTS is oil-based). It may last a bit longer than Bifen IT, but would have similar residual to Bifen XTS. Great options for longer residual in more severe weather would be either Suspend Polyzone or Cyzmic CS.
